PNG Display Messed up on Quad

Unity Engine
1

I have a quad scaled pretty big.
I have a PNG file with transparency.

When I apply the PNG to the quad it looks fine initially.
If I turn on “Alpha is Transparent” and click Apply the texture on the quad is messed up.
It may be displaying a very small part of the map blown up very large, I can’t tell.
Note: The preview shows the texture properly with the checkerboard showing through in the alpha areas.

Anyone have a clue why the alpha is causing this issue?

Thanks.

Please post some screens of your import settings and quad setup, it will help diagnose.

UnityL,

Thanks for the reply.
See attached screen captures.

FYI: The texture is an old file I imported into GIMP,
added a transparency layer to and saved as a PNG.

Hope you will have some insights; I’m clueless here.

We need to see the incorrect image as well.

Dantus,

Attached is a screen capture of my camera view (identical to the scene view).
Thanks.

What is wrong with that? Do you mean that there is no transparency? You would need to use a transparent shader in that case.

Dantus,

Thanks for the response.

Here I had a long post as a response about how you misunderstood me and, lo and behold, you were perfectly correct.
I was totally mistaken about how to display a transparent texture.

I should have read the docs before I started this thread.

Appreciate your help.

So what is “Alpha is transparent” for anyway?

It is there to remove edge artifacts. It is often the case that you have white borders between the transparent and opaque parts. This flag should get rid of them.
